GPS-Lap-Timing page 2 / 14 1 Mounting the GPS mouse For optimal signal quality the GPS mouse must have a free visibility towards the GPS satellites. Therefore it should not be covered by any shielding parts. Mounting the antenna on the roof of the car or the pillion of the bike would be the best solution. To get better signal use aluminum foil as ground plane underneath the GPS mouse. Double-sided “scratch tape” or Velcro® works very well to fix the GPS module. It keeps the GPS receiver fixed on its place but can be removed easily as well. The GPS mouse also has an integrated magnet on the lower surface. This allows simple and fast mounting of the receiver on all magnetic surfaces (e.g. body parts of the vehicle). Connecting the GPS mouse µCAN-Logger - overview StickLogger - overview GPS mouse The power supply of the complete system must be switched on before testing the GPS mouse. Incoming GPS data can be displayed online in the 2D software WinIt. GPS channels Connecting the 2D GPS module to the 4 pin connector of the logger activates additional 15 GPS channels to be recorded in the logging system. It is important that the mounting instructions previously explained for the GPS module are followed exactly which will maximize the GPS signal quality. The GPS channels are as follows: V_Sat – vehicle speed according to changing of its GPS coordinates ValidSat – number of valid satellites signals being received HHMM – time of day in hours and minutes Course – the direction the vehicle is currently travelling Lat_dez – lateral GPS coordinates for vehicle position Lon_dez – longitudinal GPS coordinates for vehicle position Altitude – estimated altitude MMDD – the current date in month and day format SSHH – the current time in seconds and hundredth of a second format A_Lat – lateral acceleration of vehicle according to changing of its GPS coordinates A_Lon – longitudinal acceleration of vehicle according to changing of its GPS coordinates Banking – estimated banking angle of the vehicle when cornering YawRate – the rate at which the vehicle is changing its cornering radius SpAccu – the estimated accuracy of the GPS speed measurement LapGps – to enable lap time generation when no official circuit timing is available GPS-Lap-Timing page 3 / 14 GPS module operation mode Ensure the data logger’s “operation mode” is set according to the type of GPS module you are using. The data logger operation mode is changed by: selecting your interface/data logger from the system tree selecting the tab “Operation modes” choosing the correct option from the dropdown menu The physical appearances of each GPS module are very similar, they have a similar plastic housing and so the table below should be used when choosing the operation mode.

You must select the trigger channel that will activate the LAPTIME event inside the logger. 2.1.1 Selecting the trigger channel for LAPTIME There is only one valid channel that can be used for the trigger channel via GPS signal: LapGps. See section 2.2 Creating lap times with GPS for information on configuration of LapGps for further information. To define the trigger channel, start WinIt, select your logger in the system tree, go to Channels ⇒ Event ⇒ LapTime and open the tab <Parameter>. Choose the channel “LapGps” from the drop down menu of “Channel-number”. Confirm your changes with <Apply>. 2.1.2 Defining the “Timeout” parameter for LAPTIME You must also define the “Timeout” parameter to be less than the expected lap time. This setting defines the minimum lap time that will be accepted as valid by the data logger. The timeout setting helps prevent “false” lap times being generated, if the radius is set too big. For example, if you expect lap times of 1 min 32 s, set “Timeout” as 90000= 90 seconds = 1 min 30 s! Creating lap times with GPS Lap times can be generated by the channel ‘LapGps’ using your 2D GPS module. LapGps provides an alternative lap trigger signal that can be used when it is not possible to generate lap times with other modules (e.g. the 2D infrared receiver). LapGps does not make lap times by itself, but simply generates a lap trigger signal when the GPS location of the vehicle is matching the GPS location of the defined lap trigger coordinates (start line). There are two ways of using the GPS lap trigger signal: Automatically - using the table ‘2DTrkPos’ (already loaded inside your module/µCAN data logger) Manually – you input the coordinates of your circuit start/finish line (read from line file) GPS-Lap-Timing page 5 / 14 Automatic setting of LapGps The table ‘2DTrkPos’ contains the start line coordinates of many popular race tracks from around the world. The process is automatic, but you must define a ‘radius’ around the table-defined start line coordinates, where the LapGps trigger signal is made. Find recommended values for the radius in the table below for firmware-versions from 2012 onwards. For older firmware-versions choose the double radius. To enter the radius, start WinIt, select your logger in the system tree, go to Channels ⇒ GPS ⇒ LapGps and select the tab <Laptrigger coordinates>. Confirm your changes with <Apply>. Speed at lap trigger point Recommended radius <180 km/h 25 m 180 – 240 km/h 35 m >240 km/h 45 m The GPS module compares its measured coordinates with those inside the table ‘2DTrkPos’ and generates a lap trigger signal when the vehicle passes within the defined search radius of the start/finish coordinates defined in the table. Define search radius for locating the Start line! Start line coordinates for many race circuits! The defined search radius must be large enough to accommodate different driving lines and also GPS drift. However if the search radius is too large it may be possible to generate invalid lap times due to the lap signal occurring more than once in a lap, see figure below! Correctly defined search radius Radius too big and activating lap at other part of circuit! GPS-Lap-Timing page 6 / 14 To check that your race track is inside the table ‘2DTrkPos’, check in the appendix or go to your system directory <C:\ProgramData\Race20xx.y\System\Tables> (since 2014) or <C:\Race20xx.y\System \Tables> (older versions) and open the file ‘2Dtrknme’. Inside this table you can view all the race tracks currently accommodated by the automatic function for GPS lap trigger. If your circuit is not inside the table ‘2DTrkPos’, you should first check the 2D automatic updates to ensure you have the latest version of the table! Creating or modifying a start-line You can manually define the start-line coordinates of your circuit. This is required where your circuit is not in the table ‘2Dtrknme’ or you wish to modify the position on the circuit at which you are generating lap times by GPS. If the track on which you are racing is not inside the table ‘2Dtrknme’, the automatic GPS lap trigger will not work! To manually define the coordinates of your circuit start line, you must: 1. Obtain an accurate GPS measurement of the circuit layout and start line position. Make an installation lap to measure the circuit start line coordinates. 2. Use the program 2D Analyzer to select your preferred start line position. Open your measurement in Analyzer, press <space> to enter measure-mode and put the cursor on your preferred start-line position GPS-Lap-Timing page 7 / 14 3. Use Analyzer to save your start line position to a table. Right-click with mouse on your preferred start line position, select <GPS> + <Store GPS line coordinates in GPS lap table>. The table will be stored at <C:\Race20xx.y\System\Tables>. 4. Load your GPS table into the data logger to trigger lap times by GPS. Connect to the logger and load the updated table into WinIt. The updated ‘2DTrkPos’ is loaded by clicking onto the buttons shown below depending on the license level you are working on. In the standard version the file 2DTrkPos.TBL has to be chosen whereas in the KIT version it works automatically. Send all changes to the logger with <Apply> KIT version Standard version GPS-Lap-Timing page 8 / 14 5. Usually the logger chooses the start-line which is closest to its current position when the logger is powered. If there is a need to force the logger to use a certain start-line or manually enter GPS coordinates, there is the possibility to do this in the channel LapGps. Choose the previously created start-line or enter the coordinates and send all changes to the logger with <Apply>. GPS-Lap-Timing page 9 / 14 3 Creating GPS section times To create section times via GPS you have to create the GPS section triggers first. Therefore you need GPS data of a full lap of that circuit. How to create GPS section trigger 1. Open your measurement in 2D Analyzer, press <space> to enter measure-mode and put the cursor on your preferred section trigger position 2. Right-mouse click on your preferred section trigger position (have a look at the circuit window to see where on the track you are), select <GPS> ⇒ <Add to GPS section list> and name your section trigger. 3. The window “GPS sections list” shows all available GPS section triggers of that event. 2D Analyzer checks which trigger coordinates match the current measurement and fades out other section triggers (they appear grey instead of black). To create the section triggers for the analyzing select <Create triggers>. You can choose between “Single section” (creates only one selected trigger) or “Complete sections list” (creates all valid section triggers). GPS-Lap-Timing page 10 / 14 4. In the multi-circuit window (shortcut <M>) you can see your created section triggers: 5. To be able to use these section triggers online they need to be stored in the section trigger table (2DSecPos). Click on <Store GPS section coordinates in GPS sec table>. 2D Analyzer informs you about its action and where the table is stored. GPS-Lap-Timing page 11 / 14 6. Load this 2DSecPos table to your logger. Connect your logger to your PC and start WinIt. Select Tables, Fix ⇒ 2DSecPos. Click on <Load from disk> and select the section trigger table. 7. Confirm your changes in WinIt with <Apply>. SecTime (Event channels) There is only one valid channel that can be used for the trigger channel via GPS signal: LapGps. See section 2.2 Creating lap times with GPS for information on configuration of LapGps for further information. If the lap time is generated with the “LapGps” channel, then normally the section times are also generated via GPS (provided that the table 2DSecPos is available). To define the trigger channel, start WinIt, select your logger in the system tree, go to Channels ⇒ Event ⇒ SecTime and open the tab <Parameter>. Choose the channel “LapGps” from the drop down menu of “Channel-number”. The timeout should be less than the fastest section time. Confirm your changes with <Apply>.
